THOS. R. WHITE AND WM. G. BEDFORD, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED FABRIC FOR TUBING, 80C.

Specification forming part of Letters Patent No. 57,233, dated August 14,1866.

To all whom it may concern:

Be it known that we, THOMAS R. WHITE and WILLIAM G. BEDFORD, of Philadelphia, Pennsylvania, have invented a new Fabric; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accolnpanyin g drawings, and to the letters of referen ce marked thereon.

Our invention consists of a fabric composed of threads and wires interwoven and coated with water proof material, substantially as described hereinafter, the said fabric being strong, durable, andlight in weight, and especially serviceable for forming tubes to be used with drills for boring Artesian wells.

In order to enable others skilled in the art` to which this most nearly appertains to make our inventiomwe will now proceed to describe the manner ot' carrying it into effect.

On reference to theaccom pan yin g drawings, which form a part of this specification, Figure l represents a piece of our improved fabric with portions of the coverings broken away to show the mannerin which itis made, and Fig. 2 a section on the line l 2, Fig. l.

The warp of the fabric consists ot' a series of parallel wires, a a, and the weft of threads c c, of any librous material, the two being woven together in a loom. The fabric of Wire and threads thus interwoven is passed through a solution of india-rubber, gutta-percha, or other water-proof material or composition, which adheres to the fabric in the form of athin coating, d. A thin sheet, e,of rubber or other suitable material is then applied to each side of the newly-coated fabric, and the whole is passed between rollers 'so arranged as to exert upon it an exceedingly heavy pressure, the rubber sheets being thus caused to adhere firmly to the coating d. The new fabric thus formed is ready for use as soon as it leaves the rollers.

The fabric, although applicable to many purposes, is especially serviceable for forming tubes to be used in connection with drills for boring Artesian wells, the wires a a running lengthwise in the tube and imparting such strength to the latter that it will not only support the weight of the drill but that also of a column of water and detritus, which is raised through the tube by the motion of the latter in conjunction with valves in the saine. Although tubes thus constructed are strong and durable, they are light in weight and may be readily wound onthe usual drum.

In some instances it will be best to use a fabric in which the warp is composed of threads and the weft of wire; or both the warp and weft may consist of both threads and wire.

We claim as our'invention and desire to secure by Letters Patent- As a new manufacture, a fabric composed of threads and wires interwoven and coated with a waterproof material, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.

THOS. R. WHITE. WIM. G. BEDFORD.
